IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
This paper presents a new approach to the extraction of straight lines in intensity images. Pixels are grouped into line-support regions of similar gradient orientation, and then the structure of the associated intensity surface is used to determine the location and properties of the edge.

Digital Straight Line Segments
IEEE Transactions on Computers, 1974It is shown that a digital arc S is the digitization of a straight line segment if and only if it has the "chord property:" the line segment joining any two points of S lies everywhere within distance 1 of S. This result is used to derive several regularity properties of digitizations of straight line segments.

Perception, 2007
In this research, we set out to investigate haptically perceived space. Large deviations with respect to physical space have already been shown to exist. Here, research on haptic space is continued by investigating straight lines constructed by touch. In four experiments, subjects were asked to produce straight lines between two reference markers that

Case (ii), Table 12.1 assumes correct abscissas and repeatedly measured ordinates. As now the empirical variances of the ordinates are directly accessible the scattering of the random errors may vary from ordinate to ordinate.

Computer Vision, Graphics, and Image Processing, 1988
Abstract The paper presents a new approach to match straight line segments extracted from image pairs. Important information can be obtained from the location of a pair of corresponding lines, such as distance from the camera and relative movement. Other line matching methods rely primarily on correspondence constraints to determine matches.

Straight line graphs are used when the value of each variable changes at exactly the same rate, such as an hourly wage (without overtime) and the number of hours worked. Say the hourly wage is £3. The total wage for 10 hours’ work would be £30 (£3 × 10 = £30). For 20 hours, it would be £60 — twice as much. What would the total wage be for 15 hours?
